Define: inet port exhaustion?

During various load tests within our environment, I'm seeing the following errors in our logs:

 

 

p-bigip1 local/tmm crit tmm[5406]: 01010201:2: Inet port exhaustion on 199.83.xx.xx to 10.2.1.140:7304 (proto 6)

 

 

I'm having little luck actually getting a definition of what it means - I assumed it meant number of connections are maxed out on a port...

 

 

Could someone please help with:

 

* General definition of port exhaustion

 

* Is there a known limit? Or, depends on hardware?

 

* Is the limit, per Port/per VIP? Can one port on one VIP being exhausted cause issues with other VIPs or the LTM in general?

 

 

Thanks so much,

    • Hi Experts Apart from any SNAT configuration for DNS, will the F5 throw any such errors? For example, if F5 acts in line and forwards DNS traffic in L3 forwarding mode? Sample logs given below, it does not have the SNAT IP pool.
